March - More Launches!

We launched and launched and launched.  We were getting a ton of data and running out of motors.

One thing we were noticing again was our simulations in RockSim weren't matching our data.  We needed to call a team meeting to discuss.

Wednesday, March 11th.

We worked hard trying to figure out what was wrong with our data.  We worked well into the night (on a school night no less) working with our Mentor, Ms. Hernandez.  We did many calculations and entries in RockSim.  We decided to launch on the following Saturday.




Saturday, March 14th we launched more and got more data to use:

Flight #1:
Altitude: 815ft
Time: 1m 9s
Total Mass of Rocket: 536g (ballast 60g/45g)
Temp: 58
Wind: 2 mph
Humidity: 34%

Flight #2:
Altitude: 871ft
Time: 1m 25s
Total Mass of Rocket: 557g (ballast 80g/40g)
Temp: 58
Winds 5 mph
Humidity: 29%

The motors were both from the same bag. So we increased the ballast by 25g for the second flight and it flew higher by 56ft. We didn't understand how to deal with this issue as we continued to run into the same problem. 

On a positive note, we have learned how to use the Copperhead igniters.  :-)
